Sammanfattning

Objective: Fenestrated endovascular aortic aneurysm repair (FEVAR) for juxtarenal aortic aneurysm (jAAA) disease is safe and effective with good short- and mid-term outcomes. The durability issues have mainly focused on the proximal and distal seal and target vessel (TV) instability, and long-term data are scarce. In previous studies, we have reported the short-term outcomes after FEVAR and compared our early and late experience and the long-term results for the early cohort. In the present report, we have provided the long-term outcomes for our late experience cohort who had undergone FEVAR at the Vascular Center (Skåne University Hospital, Malmö, Sweden). Methods: Consecutive patients who had undergone FEVAR for jAAAs from 2007 to 2011 were included in the present study. Data were collected retrospectively from the medical and imaging records. The follow-up protocol consisted of a clinical examination 1 month postoperatively and computed tomography angiography combined with plain abdominal radiography at 1 and 12 months and annually thereafter. The primary endpoints were TV instability, reinterventions, and survival. Changes in the aneurysm diameter and renal function and the incidence and type of endoleaks were also analyzed. Results: A total of 94 patients were included in the present study. The median follow-up time was 89 months (range, 0-152 months). A total of 280 fenestrations or scallops were used, of which 205 were stented. Technical success was 89.4%. Primary TV patency was 94% ± 1% at 1 year, 90% ± 2% at 3 years, and 89% ± 2% at 5 years. Of the 94 patients, 37 (39.4%) had required a total of 70 reinterventions. The mean time to the first reintervention was 21 ± 3.97 months. Five patients (5.3%) had died of aneurysm-related causes. Overall survival was 95.7% ± 2.1% at 1 year, 87.1% ± 3.5% at 3 years, and 71.0% ± 4.7% at 5 years. A stable or decreasing aortic diameter after treatment was seen in 91% of the cases. The mean glomerular filtration rate had decreased from 59.2 ± 14.9 mL/min/1.73 m2 preoperatively to 50.0 ± 18.6 mL/min/1.73 m2 at the end of follow-up. Conclusions: The results of the present study have shown that the long-term results after treatment of jAAAs with FEVAR remain good and the treatment is safe and effective. Although the need for reintervention remained high, long-term renal function and survival support the use of FEVAR as a valid treatment option for jAAA disease.
